REVERSIBLE BREATH -SHIELD.

Patented Nov. 19, 1912.

Application filed February 8, 1912. Serial No. 676,345.

To all whom it may concern Be it known that. L'REUBEN SIDEMAN, a citizen of the United States, residing at San Francisco in the county of. San Francisco and State of California, have invented a new and useful Reversible Breath-Shield, of which the following is a specification.

The device forming the subject-matter of this application, is adapted to be employed by doctors, dentists, barbers, and others, for the. purpose of preventing either the operator or, the patient from receiving the breath of the other.

The invention aims to provide novel means for mounting the shield upon the head of the wearer, so as to engage the nose, against vertical movement, and to engage the sides of the head, against horizontal movement. a

A further object of the invention is to provide the shield, along its edges, with reinforcing elements which will serve as places of attachment for the nose-piece and for the cheek-pieces. 1

The invention aims to provide novel means for pivotally assembling the cheek-pieces with the shield, and so to fashion the earengaging extremities of the cheek-pieces, that the cheek-pieces may have pivotal movement with respect to the shield, and may fit about the ears of the wearer, without putting the cheek-pieces under tension, due to transverse fiexure.

A, further object of the invention is to provide novel means for assembling the nose piece with the shield, whereby relative movement between the shield and the nosepiece will be obviated.

A further object of the invention is to provide a device of this type which may be positioned to cover the mouth of the wearer in the one instance, and to cover the nostrils of the wearer, when the shield is inverted, a single projecting member constituting at one, a nose-engaging element or a chinengaging element, adapted to support the shield in successive positions thereof.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention residesin the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without depart-- mg from the spirit of the invention.

In the accompanying drawings,Figure 1 shows the device in side elevation, applied to the head of the wearer; Fig. 2 is a perspective, parts being broken away; Fig. 3 is a rear elevation of the shield, parts being broken away; Fig. 4.- is a section upon the line A-B of Fig. 3; Fig. 5 is a section upon the line C-D of Fig. 3; and Fig. 6 is an elevatiomshowing the structure positioned difierently upon the head of the wearer, from the disclosure of Fig. 1.

In carrying out the invention there is provided a shield 1, which may be of any form. The shield 1, if desired, may be provided with an opening 2, approximately triangular, or of any other form. The lateral edges 3 of the shield 1 are concaved, and converge, to define a blunted point i at the lower end of the shield 1. The upper edge of the shield consists of two concaved portions 5, serving to shorten materially the upper edge of the shield. Intermediate the edges 3 and 5, the lateral extremities of the shield are curved to form side sockets 6, provided with transverse slots 7 That port-ion of the upper edge of the shield which lies between the concaved edges 5 is rolled upon itself to form a top socket 8. The shield 1 is provided, along the edges 3 and 5, with integrally formedtongues 9 which are bent to overlie the rear face of the shield, as clearly shown in Fig. 3. The tongues 9 serve to retain in place, a sheet of transparent material, serving as a closure for the opening 2, the sheet of transparent material being denoted by the numeral 10, and being fashioned, preferably, from mica or othertough,

'yieldable, transparent material.

The invention further includes an arched nose-piece, denoted generally by the numeral 11. The nose-piece 11 includes a crown 12, and diverging resilient arms 14, the crown 12 being disposed preferably at right angles to the plane of the arms 14. The extremities of the arms 14 terminate in axially alined fingers 15, adapted to be inserted into the ends of the top'socket 8. As denoted by the numeral 16, the top socket 8 and the fingers 15 are preferably curved, the construction being such that when the fingers 15 are inserted into the socket 8, the nose piece 11 will be held upon the shield 1, against rotation with the socket 8. as a center. The

ward ends, terminate in eyes 18, adapted to be mounted in the slots 7 of the side sockets 6. Retaining members, preferably taking the form ofheadecl pins 19, are inserted into the sockets 6, the pins 19 passing through the eyes 18, to afford a pivotal mounting gage the ears of the wearer.

:nose piece for the cheek-pieces 17, the slots 7 permitting the cheek-pieces 17 to be folded down upon the shield 1, after the manner of a pair of spectacles. At their rear ends, the cheek-pieces 17 terminate in ear-engaging loops 20, the free ends 21 of which are adapted to extend beneath the ears. The upper portions '22 of the loops 20 upst-and above the body portions of the cheek-pieces 17. Owing to this construction, when the device is positioned as shown in Fig. 1, it will not be necessary to place the cheekpieces 17 under tension, due to transverse flexure, in order that the loops 20 may en- The cheek pieces 17, therefore, are not bent, and consequently the pieces will, when the device is not in use, have free pivotal movement in the slots 7. .1

As will bereadily appreciated, the side sockets. 6 and. the to socket 8- serve as rein'ztorci'rig; elements or the shield 1, and serve, also, as places of attachment, respectively, for the cheek-pieces 17 and for the 11. -When the device is positioned as shown in Fig. 1, the arms 14 of the noseiece 11 will lie along the sides of the nose 0 the wearer, the crown 12 extending across the bridge of the nose. The shield will thus be prevented from vertical movement, and a horizontalmovement of the shield will be prevented, by the cheek-pieces 17 Under such circumwearer will be exposed, when the device is positioned as shown in Fig. 6.

Having thus described the invention, what is claimed is 1. A device of the class described comprising a shield having a transverse socket; an arched nose-piece having fingers to register in the ends of the socket, the socket.

and the fin ers being curved, to prevent the nose piece om rotating with the socket as 'a center; and cheek-pieces outstanding; from the shield. 4

2. A device of the class described comprising a shield adapted to cover the mouth of the wearer and having its lower, lateral edges converging to expose the eyes of the wearer when the shield is inverted to cover the nostrils; there. being a nose piece pro- I jecting from the shield at an angle to the plane of the shield and having an angularly disposed crown standing substantially parallel to the shield, the crown and the shield projecting in opposite directions, the crown being adapted to extend across the nose of the wearer when the shield is positioned to cover the mouth, and to rest a ainst the chin when the shield is positioned to cover the nostrils; and cheek pieces connected with the shield.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
